Accupro 12182435 Square End Mill 7/64 in 4 Flute Carbide

Product Description

The ACCUPRO 12182435 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous metals, hardened steels, and similar materials. It features a 7/64 inch (0.1094 inch) mill diameter, a 3/8 inch length of cut, and a 1/8 inch shank diameter, with an overall length of 1-1/2 inches. The four-flute, spiral design with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. The AlTiN coating enhances heat resistance and extends tool life in high-speed cutting applications. This end mill is centercutting, allowing direct plunge entry into the workpiece. Machinists and CNC operators working in job shop and production environments are the primary users.

This end mill is suited for slotting, profiling, and peripheral milling operations in ferrous alloys, hardened steels, stainless, and similar hard materials where an AlTiN coating provides thermal protection. Its regular length designation makes it a standard choice for general-purpose milling setups where rigidity and accuracy are priorities. The 1/8 inch shank fits standard ER and collet chuck toolholding systems common on CNC machining centers and manual mills.

Key Features

• Solid carbide micrograin substrate for high rigidity and wear resistance
• AlTiN finish for elevated heat resistance in high-speed and dry cutting conditions
• 30-degree helix spiral flute promotes chip evacuation and reduces cutting forces
• Centercutting geometry allows plunge milling without a pre-drilled pilot hole
• Right-hand cut and right-hand flute configuration for standard spindle direction
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish

Compatibility

Designed as an OEM-style replacement and standard-fit solid carbide end mill for use in 1/8 inch collet chuck or ER toolholding systems on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the collet or toolholder to the recommended gauge line and torque the retention nut per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning the cut, as excessive runout will accelerate wear on small-diameter end mills.
